Life is about growth, and to grow we need a guide, a mentor, a Teacher. A teacher is a guide who has been down the path before us. Man has been on this planet for a very long time and each generation has been a teacher to the next generation. Imagine if each generation could not teach and communicate its learning to the following generation. It is the relationship of Teacher and Student which enabled early Man to take the twig and create the flute and then the wheel. Man has learned well to teach and to learn and thus to constantly build on the knowledge which our teachers have taught us.
